About This Book

Audience

This book is written for programmers who need to design DataWindow®

objects. DataWindow objects are used to retrieve, present, and manipulate

data from a relational database or other source. You can use the

DataWindow objects that you build in DataWindow Designer to create

applications for the Microsoft .NET Framework using Sybase

DataWindow .NET™.

How to use this book

This book guides you through the process of using DataWindow Designer

to create DataWindow objects.

Related documents

For information on using DataWindow objects with the Microsoft .NET

Framework, see the DataWindow .NET Programmer's Guide.

For a complete list of books and online documentation, see the preface in

the DataWindow .NET Programmer's Guide.

About DataWindow Designer

DataWindow Designer is a tool that creates DataWindow objects for use in

applications. A DataWindow object is an object that you use to retrieve and

manipulate data from a relational database or other data source. The following

DataWindow object retrieves and updates employee data.

DataWindow Designer provides built-in connectivity to a broad range of

desktop and server-based databases. It includes the EAS Demo DB (a Sybase

Adaptive Server® Anywhere database) to create reports and other

DataWindow Designer objects.

When you work in DataWindow Designer, you work in a graphical

environment—and working with data in this environment means you do not

need to understand SQL, the standard programming language for talking to

databases. DataWindow Designer creates all SQL statements behind the scenes

as you build your DataWindow objects and other objects graphically.

Painters

In DataWindow Designer, you do most of your work in the DataWindow

painter, where you “paint” your DataWindow objects. DataWindow Designer

also has painters where you work with databases, libraries, and SQL

statements.

The DataWindow Designer environment

When you start

DataWindow Designer

the first time

In DataWindow Designer, you always work within the context of a

DataWindow project. Information about the project is stored in a text file with

the extension .dwp. The DataWindow objects you create are stored in binary

files called libraries. Library files have the extension .pbl.

To create a new project and a library to hold your DataWindow objects, click

the New button on the PowerBar and select Project from the Project tab page.
